JLD Bridge Doctor

About This Item

• Enhances volume
• Flattens 'bellied' soundboards

A unique solution to a common bridge problem, this spruce device attaches beneath a guitar bridge. An adjustable spruce "pressure post" rests against the tailblock, providing leverage to flatten the soundboard.

The spruce block is 3/4" x 1-5/8" x 3-3/8" tall. The 1/4"-diameter tension rod is 9" long. The mounting post has three different positions to accomodate a variety of bridge styles.

Screw mount: This spruce device attaches beneath the bridge via an inlaid screw (a white pearloid dot is included to hide the bridge screw). An adjustable spruce pressure post rests against the tailblock, providing leverage to flatten the soundboard. Better bridge contact and alignment can also enhance sound projection.

Brass pin mount: The pin-mounted version of the JLD Bridge Doctor attaches beneath the bridge using a threaded brass bridge pin. The strings mount horizontally through the tops of the matching brass bridge pins (included).

StewMac Tech Tip: We recommend the brass pin mount version for 12-string guitars.

I ordered the brass pin mount and put it in my Grandfather's 12-string... This guitar was badly warped with about 1 to 1 1/2" (maybe even 2"... I didn't measure.) gap between the neck and strings @ the 12 fret. It is tightened as far as it can with no movement of the top. There is only 2 stars for the fact that it was complete and i had no issues installing.

I could go on about this thing but it's all been said. Installed the screw mount in my 40 year old Hummingbird copy. I R & R'd the bridge as well. Only one problem .. had to shave 3mm off the bottom to make it fit but what an awesome response to all issues. Great product.

It saved my baby

It saved my old Epiphone flat top. Before this, the bridge would pull up and the action got quite high. No problem now

Stunning success

I took a lot of time considering and consulting 'reviews' and principles of this thing, and have a fair bit of experience with guitars, knowhow and tools to do it. The guitar is a Seagull Maritime mini jumbo and only a year old, but was slightly bellying. Mainly I wanted to prevent any further movement (and take the slight bit out) and stabalise the top. I also noted the great sound that Breedlove guitars achieve with this as standard and figured that, as a truss for the top, it would provide long term structural integrety and more stable tuning. It did all this and more, a little more sustain and 'bass' response and evenness of tone and tuning stability is great for altered tunings as the top remains constant, even with the altering of the string tensions, the others stay true to pitch. I'm confident that this top 'truss rod' will keep the top stable and strong for the life of the guitar. I'd recommend it, but be sure you have the skills and room inside for this device. Don't force the top (Mine was bearly lifting). I used and recomended the cheaper permanent install, but again, make sure there is enough room in the bridge and the underside and no pickups in the way. I used a hole punch of tortoiseshell pickguard material over a black dot and unless looking closely, the installation is invisible...see pic

good? yes & no

yes it sorted out the bulge in my Martin's plastic sheet top , it sounded tighter and seemed to fit the bill. But - the brass pins don't put much down pressure on the saddle, although the solid brass anchors maintain the sustain. After 3 months of installation and 3 weeks of being away on business, I picked up this guitar to find it had settled with two strings buzzing on the saddle. So I need to do some messing about with the truss rod or might have to shim the saddle up a tad. There goes my nice low action.

Just installed one of these on an old Yasuma that had a slight belly, and was sounding quite flat. It took 1/2 hour to install. The Bridge Doctor reduced the bellying, and greatly improved tone and sustain. As others have said, go slow with the adjustment on the post. Try humidifying the guitar and tensioning the rod slowly over a period of a few weeks.

Great Product!!!

I purchased a used guitar from an online auction. It had been abused, and had a severe pot belly but I thought it was worth saving. I had read about the JLD Bridge Doctor and decided to give it a try. The distance between the bridge pins and the back of the bridge was pretty small so I did not think I could use the screw mount version, so I ordered the Brass Pin mount version. I installed the bridge doctor and gradually tightened the pressure post over several days and the top flattened out almost perfectly. I tightened the pressure post a little over the next couple of days to compensate for the string tension. I was amazed at the brilliance, sustain and tone when I played the guitar. This was far better than I had expected. Over the next couple of weeks, I would have to adjust the tuning of the strings slightly each day as I guess the top was still settling in. Now I seldom have to re-tune as it holds the tuning very well. It has been 6 weeks since I strung it up and it still sounds just like it has a new set of strings even though I play it every day. This guitar sounds better than any of my other 7 guitars which include high-end models. I would definitely recommend the JLD Bridge Doctor. I am considering installing it in my other guitars to see if it will improve their tonal qualities even though I donÆt have any pot belly problems with them.

Very useful!

My 77 Yamaha FG-340's bridge was bowing badly and the guitar played poorly. I installed one of these and adjusted it progressively as the guitar sat there with no strings on. After a week or so, I restrung the instrument and it has been a gem to play ever since... Very neat invention that thing is... :)

THE acoustic saver

I've used the Bridge Doctor on guitars from the 60's, Spanish, and even Ovations. It never ceases to amaze me in how it can bring the belly down in an acoustic. It's simple to install, creates a beautiful sustain and resonates outstandingly in any acoustic you put it in!

I bought one of these to fix a belly in an old guitar and the installation was straightforward and it seems to have fixed the belly. I will use one of these to remove the belly from a 12 string guitar in the near future and I expect a similar result, a good bit of kit.
